....youre lying arent you? Weird its almost like Ive seen these kinds of requests before or something.
Give linkedin a call, or check 'your email'. Theyre not just gunna lock someone out of their account permanently just cause of some failed log in attempts. Id be a DoS hayday with people locking out everyones accounts if so. Theres gunna be a number to call, an email to respond to, or something in order to verify who you are and unlock the account.
Since you don't know this you are either stupid, lying, or the most probable: both.
